Sita

Sita was a Human pilot from Mars, who was married to Corbin's father Marcus.

Sita met Marcus as a pilot of the supply shuttle to Overlook, a lab on the surface of Enceladus where Marcus was stationed. He fell in love with her and invited her in for a date. As Overlook did not have a decontamination flash suitable for Humans, her presence broke contamination protocols and got them both fired. Sita found new work with a cargo company on Titan and got married to Marcus. Shortly after she told him she was pregnant, Sita and her unborn child died during a run from Titan to Earth due to improperly sealed ambi cells.

Marcus, overcome with grief and convinced that there was no other way for him to start a family, took all his savings to Stitch and had himself cloned.
